Austenite grain growth and effect of austenite grain size on bainitic transformation
Materials Science and Technology, 2022 This study was carried out with medium carbon steel to investigate the austenite grain growth kinetics at three temperatures and the effect of prior austenite grain size on bainitic transformation kinetics. Grain growth behaviour of austenite with two initial microstructures, pearlite and bainite, have shown almost similar kinetics.

Austenite grain growth simulation considering the solute-drag effect and pinning effect [PDF]
Science and Technology of Advanced Materials, 2017 The pinning effect is useful for restraining austenite grain growth in low alloy steel and improving heat affected zone toughness in welded joints. We propose a new calculation model for predicting austenite grain growth behavior.

The Effect of Precipitate Evolution on Austenite Grain Growth in RAFM Steel. [PDF]
Materials (Basel), 2017 To study the effects of various types of precipitates and precipitate evolution behavior on austenite (size and phase fraction) in reduced activation ferritic/martensitic (RAFM) steel, RAFM steel was heated to various austenitizing temperatures. The microstructures of specimens were observed using optical microscopy (OM) and transmission electron ...

Three-dimensional cellular automaton simulation of austenite grain growth of Fe-1C-1.5Cr alloy steel
Journal of Materials Research and Technology, 2020 A three-dimensional (3D) cellular automaton model describing the austenite grain growth process of Fe-1C-1.5Cr alloy steel is established. This model proposes a discrete representation of the three-dimensional grain boundary curvature, and calculates the
